Product Description: The 390-560 is a high-stability 45° tangential knife blade, precision-engineered for the advanced T-Series cutting heads of Summa digital plotters and F-Series flatbed systems. This blade is specifically distinguished by its specialized 40/25° wedge geometry, which provides significantly more mechanical support at the cutting tip than standard blades. This structural reinforcement makes the 390-560 the primary choice for processing thicker, more resilient substrates that would cause thinner blades to deflect or break.

With a versatile 45° cutting angle and an increased maximum cutting depth of 1.00 mm, this blade bridges the gap between delicate kiss-cutting and heavy-duty through-cutting. It is highly optimized for technical materials, including high-intensity reflective foils, magnetic vinyl, and heavy masking films used in sandblasting and industrial signage. The tangential steering of the Summa T-head ensures that this robust wedge profile navigates tight corners and complex geometries with total precision, preventing material tearing. Manufactured from high-density tungsten carbide, the 390-560 offers exceptional thermal stability and wear resistance, maintaining a razor-sharp edge through demanding production cycles of abrasive and dense substrates.
